RAZOR-STROP.

SPECIFICATION forming part of Letters Patent No. 551,331, dated December10, 1895.

Application filed January 11,1895. Serial No. 534,512 (No model.)

To all whom, it may concern 3e it known that I, HARDING F. GRAY, acitizen of the United States, and a resident of Passaic, in the countyof Passaic and State of New Jersey, have invented a certain new anduseful Improved Razor-Strep, of which the following is a specification.

My invention relates to razor-strops put up in a form convenient fortravelers, the object being to provide the usual and popular form ofloose strop with a casing in which it may be stored when not in use andproviding for making it automatically returnable into the casing whennot in use.

\Vith this object in view my invention consists in the construction andcombination of parts, as hereinafter fully described, and set forth inthe claims.

In the accompanying drawings, which form a part of this specification,Figure 1 represents an axial longitudinal section of my strop rolled upwithin its casing. Fig. 2 represents a transverse section of said strop.Fig. 3 represents an end view of the hollow roller and an end platetherefor. Fig. at represents in transverse section two forms of strop.

In the drawings, A. indicates the casing for V the strop, which may bemade of any material desired and ornamented in any suitable manner. Thiscasing is provided with a ring B, by which it may be hung upon anysuitable hook.

Within the casing is mounted a hollow roller 0. Upon this roller issecured the strop D, which has at its end the usual holdingloop E, aslit, as F, being formed in the easing from which the end of the stropbearing said loop protrudes.

It will be noticed that the roller G is so constructed that it is ofgreater diameter at its middle point than at any other, thereby causingit to taper gradually toward its ends. This point of greater diametercoincides with the longitudinal middle line of the strop. This form ofroller provides for an even return of the strop within the casing.

The hollow rollermay be mounted in various ways within the casing andthe spring for returning the strop to place may be constructed andlocated difterently from the form shown in the drawings; but I prefer touse the construction as illustrated. In this construction a right-handedscrew, as G, is inserted through one head of the easing into the centerof the hollow roller and a lefthanded screw H is inserted into saidroller through the other head of the casing. These screws are securedagainst rotation in said head in any suitable manner, being shown in thedrawings as square at the point of union between them and said heads.Upon each screw is placed a nut I, which is of such formation(preferably circular and provided with projections) as to co-operatewith suitable guides formed on the interior of the roller 0. Each ofsaid nuts in the construction shown consists of a ring through whichpass pins 5. These pins at their outer ends project into theguiding-grooves (3, formed in the inner surface of said roller, whichgrooves extend longitudinally of the roller, as shown. Said pins alsoenter the central opening of the ring and project into the threads ofthe screws G and H. The threads of these screws are of coarse pitch andthere are by preference two threads upon each screw. About each screw isplaced a spiral spring K. This spring bears against the nut I at one endand a suitable abutment at the other, preferably a plate, as L, providedwith lugs fitting into notches in the end of said roller, so that thesaid plate may turn with the rollers and thereby provide against anytorsional strain upon the springs K, such as would result from theirbearing directly upon the heads of the casing. Suit-able stops, as 7,are placed at the inner ends of the screws G and H to limit the movementof the nuts I.

I have shown the heads of the casing as screwed upon the body portion,but obviously they may be connected thereto in any other suitablemanner.

The parts as shown have been specially designed for convenience inassembling them. Their form and shape may be varied, if desired, inorder to facilitate the mode of manufacture and assembling withoutdeparting from my invention.

The operation of the improved article is as follows: In the drawings thestrop is shown in its normal position. When it is to be used the case ishung upon some suitable hook and by pulling upon the loop E the stropmay be drawn out, which act causes the roller C to revolve, carryingwith it the nuts I, which travel around their respective screws, therebycompressing the springs K. Upon releasing the strep it will again berolled up,

because of the sprin s K expanding and forcing the nuts I along thescrews, thereby r0- tating the roller C. One screw and one nut might beused, but two are preferable, as by them a steady and even action of theroller 0 is obtained.

The strep which I prefer to use consists of a strip of leather M, havingformed upon one side thereof a fold of porous material such as canvas orany other substance 0 which shall readily allow a finely-powdered orsemi-plastic abrading material to pass through its meshes or pores.Between such porous material and the leather or within the fold madeentirely of said material, as shown at O, I place the abrading materialP. This constitutes the rough side of the strop while the leatherfurnishes the smooth or finishing side.

\Vhat I claim as my invention is- 1. The combination, substantiallydescribed, of a hollow roller provided with guides extendinglongitudinally of its inner surface, a nut fitted to slide along saidguides. a fixed screw within said roller upon which said nut is free toturn, a spring exerting its tension upon said nut, and a razor strepsecured to said roller and adapted to be rolled thereupon by the actionof said spring.

The combination with the casing, of the hollow roller therein providedwith longitudiiial grooves on its interior, a right-handed screw fixedin one end of the casing and extended into said roller, a lefthandedscrew fixed in the other end of the casing and also extended into theroller, a nut upon. each screw provided with projections fitted to slidein said grooves, a spring about each scre acting upon its respective nutto force it along the same, and a razor strep connected to said rollerand. adapted to be wound thereupon by the co-action of said springs.

Signed at New York, in the county of New York and State of New York,this 10th dav of January, A. D. 1895.
